Open Wallet Standard launches; Anthropic builds AI OS
MoonPay published the Open Wallet Standard (OWS), an MIT-licensed, open-source protocol that standardizes a single encrypted wallet/vault for AI agents to hold funds, sign transactions, and pay across multiple blockchains. OWS defines seven modular sub-specifications, ships Node.js and Python SDKs, and includes AES-256-GCM encryption, locked-memory key handling, policy enforcement, and multi-chain address derivation. The newsletter also reports that Anthropic updated Claude’s mobile client to embed interactive, live instances of enterprise tools (Figma, Canva, Amplitude, Slack, Asana, Box), signaling a shift from a chatbot product to an “AI operating system” built on its MCP (Model Context Protocol). Additional brief items include Aviva launching an insurance app on ChatGPT, Aveni creating an Agent Assurance Expert Council, Bank of Ireland AI upskilling, and funding rounds for Kalshi, Spade, and Payy.
OWS fills a previously missing wallet primitive in the agent payment stack and, together with payment protocols (x402, MPP) and Anthropic's move toward an AI OS, materially advances infrastructure for machine-to-machine commerce and enterprise AI workflows.

Wealthfront Profitable but Cash Engine Vulnerable; MoonPay Ships Agent Wallet Standard
Wealthfront reported FY2026 revenue of $365 million (+18% YoY), adjusted EBITDA of $170.7 million (47% margin), and $151 million in free cash flow, with a debt-free balance sheet holding $441 million in cash post-IPO. The newsletter flags a structural vulnerability: roughly 74% of Wealthfront’s revenue is rate-sensitive cash management, and a governance controversy over the CEO’s personal ownership of a home-lending subsidiary has attracted securities‑law scrutiny and pressured the stock below 60% of its $14 IPO price. Separately, MoonPay released the Open Wallet Standard, an MIT‑licensed open-source protocol that provides a single encrypted vault enabling AI agents to hold funds, sign transactions, and pay across major blockchains. The piece also notes related coverage of Revolut’s 2025 financials and Stripe’s role in enabling machine-to-machine payments for an emerging “machine economy.”
Token Becomes the Unit of Account in AI
This newsletter summarizes a week of AI industry developments emphasizing a shift toward token-based economics. Anthropic released Claude Opus 4.8 and disclosed rapid revenue growth while raising a $65B Series H at a ~$965B post-money valuation. Anthropic’s Opus 4.8 introduces agentic and governance features (effort control, dynamic workflows, improved self-checking) aimed at long-running agentic tasks. Infrastructure and routing firms are monetizing by token throughput: OpenRouter raised $113M at a $1.3B valuation as weekly token throughput rose to 25 trillion, and Cognition raised $1B (≈$26B valuation) reporting a $492M run-rate and heavy reliance on its coding agent Devin. Snowflake committed $6B to AWS and acquired Natoma to support agentic data access. The piece links these commercial trends to ethical concerns raised by Pope Leo XIV’s encyclical about technology disintermediating human judgment.
OpenAI Shuts Down Sora; Anthropic Leads Code
OpenAI has shut down its Sora product across app, API and ChatGPT video features after demand declined. At the same time Anthropic’s Claude Code reportedly captured a plurality of the AI coding market (estimated ~42–54%), while OpenAI holds roughly ~20% and trails in U.S. developer usage. The newsletter frames coding as the highest-value AI workload, favoring providers that focused on enterprise workflows. The piece also highlights emerging industry shifts: token-based budgets for engineer model usage (tokenized compensation), Anthropic productizing Claude Code into a managed execution environment similar to OpenClaw but more closed, and Norway’s $2.1 trillion sovereign wealth fund preparing to permit limited agent-driven investment decisions using Anthropic’s Claude under human supervision. The report lists additional AI-related headlines (legal, platform competition, and product launches) and argues these developments could reshape where the agent and software stack is defined.
